I was in a parking lot and put the car in reverse. Then I heard a "boom" and I thought that I backed into something, so I quickly put the car into drive. I then felt the car excelerating fast and I was pushing the brake as hard as I could and could not stop the car from moving forward. The car proceeded to excellerate and when over a curb up onto pavement and through a metal fence and bent a 5 inch round metal fencing down to the ground and the car kept going another 30 feet till it finally stopped. You can see the skid marks in the the parking lot.

We flew to sea tac (seattle wa ) airport from slc ut. We planned on attending a family gathering and rented a car from hertz. We have owned a 2006 Prius and asked if they might have a new model to rent for comparison on our part, which they did, however it turned out to be a Prius C, which was not at all like our Prius. The traffic on the freeway was stop and go slow on a multi lane freeway and were on an inner lane. ( I - 405 North bound ) as I rolled up to what might have been a stopping situation the traffic started to move forward, and as I stepped on the pedal to move forward, I noticed that nothing was happening and the car soon came to a complete stop. The car was absent and visible power, no visual information on the mph screen, the emergency light would not work, I was nervous and scared and everything had gone dark, I did not what to do, I tried to move the key position the cars behind me started to honk, and they were also trying to get around me, just as I was starting to call 911 for some help the car powered back up with a message to put the car in park and start the motor I moved out of the situation and got off the freeway and took backroads to reach the motel, with the intent to never drive this car again, the next am I called hertz and they made arrangements to trade the car out at our motel, which they did. The tow truck driver indicated that the problem on this specific car was caused by its software and he was aware of other drivers facing the same situation, but I should count my blessing that I was not involved in a major accident I do not think this car should ever be allowed on our roads just based on this experience.

Shortly after purchasing my 2014 Toyota Prius in June 2014, I started noticing a moldy smell coming from the air conditioner. The hotter outside it got, the worse the smell inside got. I took the car to the dealer to discuss the problem with them. They informed me that Toyota says this is an "environmental issue" and can happen in new cars and is therefore not warrantied. The service manager installed a charcoal air filter in the cabin air filter and said that it would help eliminate the odor. It did not. In fact, the charcoal air filter reduced the air flow into the cabin which caused the ac to not cool. I had the service department replace the charcoal with an original air filter in September after complaining that the ac wasn't cool. The smell in the ac persists. It's not just a bit when the car is turned on. No matter what setting I put the ac on, it does not help (fresh air or recirc). When it rains or when it is really humid outside, the car smells like a swamp (even before it is turned on). There is also humidity inside the car when opening the door. I've asked multiple times to have the evaporator replaced because I fear that it is not draining and causing mold and mildew to form. Breathing in the mold is a serious health concern and Toyota will not agree to any kind of fix. I'm also having other various HVAC problems such as continuously fogging windows and a draft from the drivers side door. The car does not hold heat and is very cold during the winter months.

2014 Toyota Prius. Consumer writes in regards to push start ignition system. The consumer stated the vehicle belongs to his parents. He noticed the engine turned on by itself. He was able to open the door and noticed the power push button was lit which indicated the engine was on. The screen on the center console stated no key was detected. He pressed the power button to turn the engine off. The dealer informed the consumer, if he walked away from the vehicle without turning off the ignition, the vehicle would stay on. The engine turned on because the vehicle was in battery mode to replenish the battery power, when the system detects the battery charge has dropped below a certain level.

2014 Toyota Prius. Consumer writes in regards to engine failure. The consumer stated a brown colored alarm appeared on the dash, which flashed on then off, as the vehicle started to slow down. If he tried to accelerate, the light would come on, but no response to increase speed. He managed to pull over, and stopped the vehicle. After a few seconds, he tried to re-start the engine and was successful. The dealer was unable to duplicate, the problem the consumer experienced.

Point sources of light (I.e. brake lights, headlights, traffic lights, etc.) at night time and to a less visible extent in the day time are duplicated or triplicated at distances through the front windshield. As the light source is closer to the car, the ghosting effect diminishes. This problem does not occur when looking out the side windows or rear windshield, but only occurs through the front windshield. This prism effect induces nausea and is incredibly distracting while driving.

I purchased a 2014 Toyota Prius on May 31, 2014. Today 6/18/14 I found out there was a recall on this model vehicle. I called Toyota and I was informed the recall service had not been performed. I called a local dealer (different from the one where I purchased the vehicle) and they informed me that when they pulled the VIN, it showed stop sale in effect. I do not blame Toyota as obviously if one dealer could see the stop sale so could the other. I think that there should be stricter regulations on dealerships to make sure these recalls are completed before the sale!! just like the gentleman that complained earlier I also purchased a brand new defective vehicle, how can this happen several months after the recall. !! now I have to take the time off to take it in to have the recall fixed. This is a major inconvenience, loss of use of vehicle and loss of time from work. I also want to know how to get compensated for the inconvenience and time, plus the fact they sold and I have been driving an unsafe vehicle.
